The present invention provides a toner resin composition and toner which is superior in terms of low temperature fixation and superior anti-offset, anti-aggregation and anti-smearing properties, by introducing in the binder which is primarily composed of vinyl copolymer, a vinyl copolymer which has, in its molecular weight distribution curve, at least a peak in the range of 1.times.10.sup.3 -8.times.10.sup.4, plus a peak or a shoulder in the range of 1.times.10.sup.5 -4.times.10.sup.6, or a Mw/Mn of 6 or more, or 5 wt % or more of a toluene nonsoluble component, and 1-50 wt % of a specific ethylene copolymer.
